UNITED STATES PATENT OFFICE.

WILLIAM M. HENDERSON, OF HIGH SPIRE, PENNSYLVANIA, ASSIGNOR TO THE PENN- SYLVANIA STEEL COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

. MOVABLE-POINT CROSSING.

Specification of Letters Patent.

Patented Nov. 17, 1908.

To all whom it may concern:

Be it known that I, WILLIAM M. HENDER- SON, citizen of the United States, and a resident of the State of Pennsylvania, county of Dauphin, town of High Spire, have invented certain new and useful Improvements in Movable-Point Crossings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which Figure 1 is a plan view of a movable-point crossing, showing my invention applied thereto. Fig. 2- is an enlarged plan View,

. partially broken away, of one of the continuous traclerails, showing the hard-metal wear-piece constituting the knuckle thereof, and the means for securing it in place to the rail. Fig. 3 is a section on the line ov, Fig. 2. Fig. 4 is a section on the line a:w, Fig. 2. Fig. 5 is a section 011 the line 1 Fig. 2. Fig. 6 is a section on the line zz, Fig. 2.

The object of this invention is to provide, in a movable-point crossing, a hard-metal wear-piece at the knuckles of the con tinuous track-rails, whereby the life of said track-rails is very materially lengthened.

In carrying out my invention, I cut away the inner portion of the head of the continuous track-rail, and bend the said rail slightly outwardly, and secure to the inner side of said rail a hard-metal piece, whose inner edges are in line with the gage lines of the continuous track-rail head; the apex, or knuckle, being formed by the meeting of the said edges of said wear-piece, at a point adjlacent the points of the movable point ra1 s.

The precise character of the invention will appear from the following description :1 designates the main or track-rail, which is bent outwardly from points 2, to the rear of the points 3, of the movable-point rails, 4, as seen in Fig. 1. The inner portion of the head of this bent-out part of the track-rail, 1, is cut away, as seen in the drawings, to form a recess, within which is inserted a hard-metal piece, 5, the upper surface of whose head is in line with the surface of the head of the track-rail, 1, and whose inner edges are in line with the gage lines of the respective portions of the track-rail at either side of the points 3. Said inner edges of said wear-piece meet at a point, 6, to form the usual knuckle between the points, 3, of the adjacent opposite point-rails, 1. The wear-piece, 5, is provided with a web, 7 having bosses, 8, that abut against the web of the track-rail, 1, and beyond the head portion of the wear-piece, at each end thereof, the web, 7, is extended beneath the head of the track-rail, 1, and lies against the web of said track-rail, as seen in Figs. 2 and 6. Extending throughout the length of the wear-piece, 5, and against the web, 7, thereof, is a rolled steel supporting strap, 9, and a similar strap, 10, is provided on the exte rior of the web of the track-rail, 1. Bolts, 11, pass through these straps, webs, and bosses, to secure the said parts firmly together, all as seen in Figs. 2 and 3.

It will be observed, by the above described construction, that, not only do I provide a hard-metal bearing surface for the wheels passing over the crossing, but the hard-metal piece, 5, is supported, and the whole structure strengthened, by making the track-rail,

1, continuous throughout its length, as seen. Also, the straps, 9 and 10, serve to further support and strengthen the structure, so that if, for any reason, the hard-metal piece, 5, should be fractured, it would still be supported and held in place by its securing means; which is a desideratum in structures of this character, as the hard-metal piece would usually be made of cast metal.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent In a movable-point crossing, the combination, with the movable-point rails, of the unbroken track-rail, bent outwardly opposite the points of said point-rails, and the inner side of the head of said track-rail, at said bent-out portion, being cut away; together with the hard-metal wear-piece fitted to said cut-away portion, and the inner edges of the same to the Web of the track-rail, substan- 10 head of which wear-piece are in line with the tially as set forth.
